產(chǎn)品介紹

Product index

The TMI3351 is an integrates 2-switchs ? Computer Peripherals synchronous buck converter mainly for widely varying input step-down regulator applications. The control method is based upon current mode control that enables maximum performance under transient conditions. The output voltage can be programmed by the FB pin. It operates as a Buck mode while the input voltage is sufficiently greater than the regulated output voltage and transitions to the low dropout operation mode with maximum duty cycle at 99.5% as the input voltage very approaches the output voltage.
